Abstract:
The present invention relates to a method for a base station transmitting a precoded signal to user equipment in a wireless communication system supporting a multi-antenna. More specifically, precoding is conducted by using a precoding matrix to which large delay-cyclic delay diversity (LD-CDD) is applied, wherein the precoding matrix is determined by dividing into matrices for a horizontal direction antenna and a perpendicular direction antenna.
Abstract:
The present invention relates to a method for feeding back, by a terminal, channel status information (CSI) in a wireless communication system. In detail, the method includes the steps of feeding back a subband channel quality indication (CQI) and a subband precoding matrix index (PMI), wherein a first subband size for the subband CQI and a second subband size for the subband PMI are set differently.
Abstract:
Disclosed in the present application is a method for transmitting, by a terminal, an uplink signal to a base station through a plurality of antenna ports in a wireless communication system. Specifically, the method comprises the steps of: transmitting, to the base station, uplink reference signals corresponding to the plurality of antenna ports and antenna port grouping information: receiving, from the base station, information on an uplink precoder, which is determined on the basis of the uplink reference signals and the antenna port group information; precoding the uplink signal using the information on the uplink precoder; and transmitting the precoded uplink signal to the base station, wherein the antenna port grouping information comprises information on antenna port groups comprising the plurality of antenna ports and information of the signal distortion level between the antenna port groups.
Abstract:
The present invention provides a vehicle-to-X (V2X) operation method performed by a V2X terminal in a wireless communication system, the method comprising: selecting, in a selection period, a subframe excluding a subframe relating to a subframe in which transmission has been performed during a sensing period; and performing a V2X communication on the basis of the selected subframe.
Abstract:
The present invention relates to a signal transceiving method and device for a terminal dual-connected to a first radio access technology (RAT) and a second RAT in a wireless communication system, wherein the method includes: a step for scheduling a first signal according to the first RAT and a second signal according to the second RAT so that the first signal and second signal are temporally separated; and a step for transceiving the first signal and the second signal, wherein the first signal is dropped when the first signal and the second signal overlap in a first time domain due to timing advance (TA).
